road tunnel
Subterranean vehicle corridor
A road tunnel is a tunnel designed for vehicle traffic, allowing roads to pass through mountains, under rivers, or beneath urban areas.
Road tunnels solve problems that surface routes cannot—crossing bodies of water, bypassing congested city centers, or cutting through terrain too steep for conventional roads.
The road tunnel under the harbor saves twenty minutes off the commute.
